Use alkylbenzenes.

Article Structural Optimization of Alkylbenzenes as Graphene Dispersants

Rita - This seems to be a question of more general interest as I found two closely related questions on this platform. The first one from 2017 is entitled "How to get the good coating of reduced graphene oxide on a glass substrate?" but it does not provide any suitable answers:

The second question is even older (2014) and is entitled "How can I get graphene oxide thin films on a glass substrate?" bit the answers are also not really satisfying:

After all, I think the answer provided by Yuri Mirgorod is most useful.

@Rita Joshi,

I don't think dip-coating is the way to get uniform films unless some special ink formulation is used. We did manage to use a bar coating method to get the homogenous films of reduced graphene oxides. You could use homemade one with a hotplate to use at the same time although there are some suppliers to provide such equipment too.

Thank you everyone for your valuable suggestions.
